Homework for Day 2:

Key to Aquatic Macro-invertebrates (in Utah)

Why care about aquatic macro-invertebrates?

They are indicators of water quality. Different types of macro-invertebrates tolerate different stream conditions and levels of pollution. Depending on the types of macro-invertebrates found in a stream, predictions about water quality can be made. For example, caddisflies, mayflies, and stoneflies can not live in polluted water. If these bugs are found in a stream, the water quality there is probably good. However, that doesn't mean that if these bugs are not found in a stream the water quality is bad. Other factors like temperature and flow also come into play. These bugs prefer cold rushing water, so a stream that has good water quality, but is a slow-moving stream in a desert may not have these bugs.
Aquatic macro-invertebrates are also an important part of aquatic and terrestrial food chains. They graze on algae and break down leaves and sticks that fall into the water. They are also an important food source for fish.

Water Properties

Facts and Figures About Water

Some of water's physical properties:

• Weight: 62.416 pounds/cubic foot at 32°F; 1,000 kilograms/cubic meter
• Weight: 61.998 pounds/cubic foot at 100°F; 993 kilograms/cubic meter
• Weight: 8.33 pounds/gallon; 1 kilogram/liter
• Density: 1 gram/cubic centimeter (cc) at 39.2°F, 0.95865 gram/cc at 212°F

Some water volume comparisons:

• 1 gallon = 4 quarts = 8 pints = 128 fluid ounces = 3.7854 liters
• 1 liter = 0.2642 gallons = 1.0568 quart
• 1 million gallons = 3.069 acre-feet = 133,685.64 cubic feet

Flow rates:

• 1 cubic foot/second (cfs) = 449 gallons/minute = 0.646 million gallons/day = 1.98 acre-feet/day

Water is unique in that it is the only natural substance that is found in all three physical states—liquid, solid, and gas—at the temperatures normally found on Earth.
Water freezes at 32° Fahrenheit (F) and boils at 212°F (at sea level, but 186.4° at 14,000 feet). Water is unusual in that the solid form, ice, is less dense than the liquid form, which is why ice floats.
Water is called the "universal solvent" because it dissolves more substances than any other liquid. This means that wherever water goes, either through the ground or through our bodies, it takes along valuable chemicals, minerals, and nutrients.
Pure water has a neutral pH of 7, which is neither acidic (<7) nor basic (>7).
The water molecule is highly cohesive—it is very sticky. Water is the most cohesive among the non-metallic liquids.
Pure water, which you won't ever find in the natural environment, does not conduct electricity. Water becomes a conductor once it starts dissolving substances around it.
Water has a high specific heat index—it absorbs a lot of heat before it begins to get hot. This is why water is valuable to industries and in your car's radiator as a coolant. The high specific heat index of water also helps regulate the rate at which air changes temperature, which is why the temperature change between seasons is gradual rather than sudden, especially near the oceans.
Water has a very high surface tension. In other words, water is sticky and elastic, and tends to clump together in drops rather than spread out in a thin film, like rubbing alcohol. Surface tension is responsible for capillary action, which allows water (and its dissolved substances) to move through the roots of plants and through the tiny blood vessels in our bodies.
The density of water means that sound moves through it long distances (ask a whale!). In sea water at 30°C, sound has a velocity of 1,545 meters per second (about 3,500 miles per hour).
Air pressure affects the boiling point of water, which is why it takes longer to boil and egg at Denver, Colorado than at the beach. The higher the altitude, the lower the air pressure, the lower the boiling point of water, and thus, the longer time to hard-boil an egg. At sea level water boils at 212°F (100°C), while at 5,000 feet, water boils at 202.9°F (94.9 °C).
